(6 + 7) + 8 = 21

Travka [436]

Answer: $6+(7+8)=21$

Step-by-step explanation:

1. By definition, the associative property of addition is:

$(a+b)+c=a+(b+c)$

This property says that you can group the numbers in different ways and you will obtain the same result.

2. Therefore, if you have the following expression:

$(6+7)+8=21$

You apply the Asociative property of addition by regrouping the numbers as following:

$6+(7+8)=21$

3. Then, you can conclude that the correct option is B.
